You know, I would be really great if they added two superheroines to the team, but I doubt that will happen. There will be one more woman and maybe The Falcon added next time out. My guess is that The Wasp will join, ahead of Ant-Man coming out in late 2015. I'd rather they add The Scarlet Witch, though, but Wanda may get her turn later.

I'm pretty sure that Falcon will be in Avengers 2. Falcon being a member of the new Avengers show, which has the rest of the roster being the cast of the movie, seems like pretty good proof to me.
